More milk in less time. Just like it's predecessor Swing Maxi Flex^TM, the new Swing Maxi^TM is a double pump that allows you to extract milk from both breasts simultaneously to make your pumping twice as fast. In addition, pumping both sides at the same time is proven to yield up to 18% more milk¹.

2-Phase Expression® technology. During a feeding session, babies start by using short, fast sucks to stimulate the Milk Ejection Reflex. Once the milk begins to flow, babies change to a slower, individual rhythm to actually feed. Medela's 2-Phase Expression® technology mimics baby’s natural sucking rhythms – fast to stimulate milk flow, then slower to provide optimal milk flow.

PersonalFit Flex^TM breast shield. With a 105-degree opening angle, soft rim and oval shape for a better fit, the PersonalFit Flex^TM breast shield puts less pressure on your milk ducts than traditional breast shields, resulting in a more effective and comfortable pumping experience. More comfort for you, up to 11.8% more milk for your baby – clinically proven⁴.
